Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate simple sums.

What does translating points on a number line have to do with solving inequalities? Young mathematicians first learn about translations of points on a number line, and then use this information to solve linear inequalities in one variable.

Solve any issues you have with solving linear equations. Learners solve linear equations in one variable, starting with two-step equations, in the first chapter of a 10-part eighth-grade workbook series. They then progress to equations...

You know how to find absolute values and you know how to solve inequalities — but what happens when these two concepts are in the same problem? A YouTube video first reviews absolute values and moves on to solving absolute value...

Sal uses the formula for perimeter to show how the variables can be moved around to solve a problem. He demonstrates a few different ways to do this.

One of the many methods of solving quadratic equations is graphing. A video lesson first demonstrates graphing a quadratic function using an input-output table. After graphing the parabola, the instructor makes the connection between the...

Age becomes a problem. Learners see how to set up and solve age word problems. The video goes through two examples of word problems relating the ages of people. The first example uses the relationship between the ages of two people and...

Solve this real world word problem in just one written step. The original inequality is a division problem, so to solve it, use the multiplication property of inequality. Was the problem solved by multiplying a negative number? Yes! So...

This lesson plan has a number of fun worksheets for a pre-algebra or beginning algebra class. The main emphasis of this lesson plan is functions, formulas, and looking at square roots. It is the third lesson plan in a series on solving...
